Vtil adds advanced Valkyrien Skies APIs that provides extra compatibility with other mods. Free Minecraft Java mod for 1.20.1.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

- /vtil assemble command
Connectivity API
- Provides extra information about block connectivity on ships, which can then be used in Assembly and/or ship split.
- By default wraps vanilla canSurvive, mod makers can implement IBlockAnchor and define their own block connection.
Teleport API
- Teleport valkyrien ships to another dimension with conserved velocity and omega.
- Teleport an entity and its passengers all together to another dimension, with extra mod compatibility.
